In this lab activity, students taste different samples of lemonade - rate them and then determine the molarity of sugar and citric acid in the lemonade.

In this lab experiment students are asked to determine the standard molar enthalpy of formation of magnesium oxide, MgO. Students are asked to use Hess's Law and the enthalpy changes of several other solution reactions during this...

An interactive simulation that teaches about Beer's Law, solutions, concentration, spectrophotometry, and more through observations to explore how much light is absorbed and transmitted with changes in thickness and color. This...

A collection of over 30 virtual chemistry problems with accompanying interactive activities. Each problem includes a word file for potential differentiation in your classroom.

Molarity and osmolarity are two distinct concepts. Molarity (M) is the number of moles of solute per liter of solution. The unit of molarity is the mole (mol). Osmolarity (Osm/L) is the total concentration of all solutes in the solution....

Learn how molarity and molality differ. The molality of a solution is equal to the moles of solute divided by the mass of solvent in kilograms, while the molarity of a solution is equal to the moles of solute divided by the volume of...

In this chemistry lab, young scholars will investigate a single replacement reaction while also using knowledge of molar ratios to determine percent yields.

In this activity, students use the virtual lab to prepare a sucrose solution for a soda recipe. They next calculate the concentration of their solution in terms of molarity, percent mass and density. Finally, they compare the density of...

In this activity, students use the virtual lab to create a 0.025M glucose solution from a standard 1M glucose solution. First, they calculate the correct volumes of 1M glucose solution and water to mix together to create the final 0.025M...

In this activity, students use the virtual lab to create 500mL of 3M HCl solution from a concentrated stock solution of 11.6M HCl. They must first calculate the correct volumes of 11.6M HCl solution and water to mix together to create...

In this activity, students use the virtual lab to create stock solutions starting from solid salts. Students must first calculate the correct amount of solid to make the solution. Next, they prepare the solution using the appropriate...

This virtual lab activity where students perform the method of successive dilutions using HCl, NaOH, a pH meter, and universal indicator solution to help understand the logarithmic nature of the pH scale.

See how each of these terms tells us something different about a solution.

Students use stoichiometry to determine the mass of oxygen gas in a bottle. They may also check their answer against the amount of potassium chloride produced during the reaction.

In this activity, students use the virtual lab to create dilute solutions from a concentrated stock solution of acids or bases. They must first calculate the correct volumes of concentrated acid solution and water to mix together to...

A page from the University of Maryland Physics Lecture Demonstration Facility. Provides directions for a teacher demonstration of the ideal gas law. Shows apparatus and set-up; provides suggestions. Easily adaptable as a student project...

A simple lab activity that allows good data collection on heat of solution.
